ENGINE-BASE OIL RESERVOIR.

Application filed March 14, 1925.

To all whom t may concern:

Be it known that I, AUGUSTIN RoUssELLE, a subject of the King ot Great Britain, and residing at the city of Montreal, in the Province ot Quebec, in the Dominion ot1 Canada, have invented a new and useful Engine-Base Oil Reservoir, ot which the following is the speciiication.

The invention relates to a self feeding engine base, as described in the present speciication and illustrated in the accompanying drawings, that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to maintain the supply of oil in an engine base at a definite level no matter what incline the base may be at during the progress of a vehicle or other conveyance on its way; to economize in the consumption of the lubricating fluid; to eliminate damage to the motive power through the burning of bearings; to furnish an equipment that will be applicable in any engine construction; to insure steady and efficient operation of the engine; and generally to provide a reliable and serviceable means or feeding oil automatically to the base without materially increasing the cost of the motor installation.

In the drawings, Figure 1 is an enlarged sectional view of the float mechanism controlling the valve at the primary inlet and casing forming part of the engine base.

Figure 2 is an enlarged sectional view showing the secondary valve and its float mechanism controlling the valve at the secondary inlet and the casing forming part of the engine base.

Figure 3 is a sectional detail of the primary inlet valve, showing it in its closed position.

Figure 4 is a sectional detail of the primary inlet valve at right angles to the showing in Figure 1.

Figure 5 is a sectional detail of the secondary inlet valve in its open position.

Figure 6 is a plan view of the engine base constructed with the self-feeding equipment.

Figure 7 is a perspective view of the engine base formed to contain this invention.

Like numerals of reference indicate corresponding parts in the various figures.

Serial No. 15,556.

Referring to the drawings, the engine base 10 is formed with the customary i'lange 11 and float casings 12 and 13 on either side and towards opposite ends respectively.

The side walls 14 and 15 extend through from end to end and form the inner walls of the loat casings 12 and 13 and are formed with the respective openings 16 and 17 at the bottom of said casings 12 and 13 to atl'ord free communication between float casings and the main portion of the base.

The centering pins 18 and 19 are screwed into the bottoms of the float casings 12 and 13 respectively and the floats 2O and 21, having the central pin passages 22 and 23, are mounted over said pins, which extend upwardly in said passages.

The float rods 24 and 25 extend upwardly from the floats 20 and 21 respectively and have the respective collars 26 and 27 screwed thereon.

The tapered valve 28 having the port 29 therethrough is rotatably mounted and held by the nut 30 in the valve casing 31 which is securely fastened by the nut 32 screwed on to the nipple 33 projecting through the cover 34 from the casing 31, the latter having the upper port 35 and lower port 36 adapted to register with the port 29 in the valve and forming the inlet.

The nipple 33 is threaded internally to receive the feed pipe 37 from the tank 38, thus providing, when the valve 28 is in its open position a tree passage from the tank 38 into the tube 39 which is attached to the lower outlet port 36 from the valve casing 31.

The valve operating lever 40 extends through a slot 41 in the casing 31 and is slotted at the end to engage the pins 42 from the collar 26, consequently on the lifting and lowering 'of the float the valve is operated.

The tube extends downwardly from the casing 31 and through the opening 16 and across the bottom of the base to the opening 17 and therethrough and upwardly in the float casing 13 to the valve casing 43, where it is secured to the flange 44 surrounding the entrance to the secondary inlet 45, which communicates through the valve 46 with the discharge mouth 47 emptying into the engine base 10.

The valve 46 is cored to form the communicating port 48 controlling the secondary inlet 45 and its discharge mouth 47 and by turning this valve slightly the inlet is closed and of course the discharge. yThe valve 46 is tapered and secured in the casing 43 by the nut 49 and has an operating lever 50 projecting outwardly therefrom through a limiting slot 51 in the casing 43 and this lever is slotted to engage the pins 52 projecting from the collar 27, consequently the float 21 by rising and falling with the oil closes and opens the valve 46.

The casing43 is formed with a bolt projection 53, which projects through the cover 54 and is fastened by the nut 55.

The covers 34 and 54 partly close in the float casings 12 and 13 and the cover plates 56 and 57 close the openings, remaining uncovered by said covers 34 and 54, in both cases these covers being screwed or bolted securely to the base 10.

In the operation of this invention7 the oil is usually fed bygravity from the tank 38 and Hows to the primary inlet, where it is held by the valve 28, if the vehicle is travelling'on a level road, but in the event of a slant transversely or a hill occurring in the roadway then the oil will run down towards the Icasing43 leaving the casing 31 practically free of oil or nearly so. This causes kthe ioat 2O to drop, which operates the valve 28 and opens the port leading to the tube 39, but at the secondary inlet the valve 46 again holdsup the oil and this valve is only opened on the oil swishing over to the other end or side of the base, which again closes the valve 28, so it will be seen that the two valves must be open y to supply the base andthe filling happens when the oil has dropped below the predetermined level as both floats drop, thereby turning the rotatablevalves and bringing the ports to registering positions for the oil to iiow through both inlets and empty into the base.

In this invention it will be noted that the oiling system becomes part of the engine construction and is not an accessory to the motive equipment, therefore no matter what style the engine may be so long as it has a base this construction can be added to facilitate the lubrication.

What I claim is 1. An engine base oil reservoir comprising an engine base, having its bed and walls extended at diagonally opposite points to form wells, valve casings in said wells respectively forming primary and secondary inlets and discharge, a tubular connection between said casings, an oil vsupply tank connected to said primary inlet, valves in said casings having operating stems extending through said casings and loatsin said wells, having rods therefromrop'eratively connectedwith said stems. 2. An engine base oil reservoir comprising an engine base having its bed and walls extending at diagonally opposite points to form wells, valve casings in said wells respectively forming primary and secondary inlets and discharge, a tubular connection between said casings, an oil supply tank connected to said primary inlet, a valve in said primary inlet casing having upper and lower ports adapted to register with a port passing through saidvalve, a valve in said discharge casing and floats in said wells having rods therefrom operatively connected with said wells.
